Are the children entitled to claim their deceased grandmother's inheritance after their mother's passing?

The grandchildren through a daughter have no right to their grandmother's inheritance—their mother's mother—due to the presence of other heirs. Similarly, their mother, or any heir who passed away before the grandmother, has no right to the inheritance. It is the grandmother who inherits her children who died before her. The estate belongs to the direct sons and daughters who were alive after the grandmother's death. Those who died before her, whether siblings or their children, have no right to it as long as the grandmother has a direct surviving son.
